Phase Noise Impact on Satellite Uplink and Downlink Channel Capacity

This white paper gives an overview of the critical issue of phase noise in satellite communication systems and its impact on channel capacity.  Phase noise is a significant contributor to Signal-to-Noise Ratio (SNR) and as such is an important determinant of channel capacity in any communication link. Phase noise, originating from various sources such as satellite transponders and ground equipment can significantly degrade the performance of satellite links, leading to reduced throughput and increased error rates. Understanding and mitigating phase noise is vital for optimizing satellite communication networks and ensuring efficient data transmission.

How Minimizing Pulse Droop in GaN Power Amplifiers Improves Radar Range

This article will focus on GaN PA pulse droop as a nonideality of real-world radar performance and will discuss what can be done to mitigate its negative impact on radar range. With advanced solid-state electronics inserted at the output stages for many radar RF chains, system engineers can set specifications to achieve improved range, resolution, and sensing capabilities.

Understanding Shield Effectiveness

Shielding, or screening effectiveness, is essential to the safe operation of electric vehicles (EVs). There was a time when the noise generated by the spark plugs firing in an internal combustion engine caused an annoying buzz when listening to the AM radio. Circuit designs have since evolved, and this issue was eventually resolved, but now the issue is back.

Key Parameters for Selecting RF Inductors

RF inductor selection involves these key parameters: mounting (surface mount or through-hole), inductance value, current rating, DC resistance (DCR), self-resonant frequency (SRF), Q factor, and temperature rating. While small size is typically desired, the laws of physics limit how small an inductor can be for a given application.
